FAN5193  
Two Phase Interleaved Synchronous Buck  
Converter  
Features  
Description  
• Programmable output from 1.10V to 1.85V in 25mV steps  
using an integrated 5-bit DAC  
• Two interleaved synchronous phases for maximum  
performance  
The FAN5193 is a synchronous multi-phase DC-DC control-  
ler IC which provides a highly accurate, programmable out-  
put voltage for all high-performance processors. Two  
interleaved synchronous buck regulator phases with built-in  
current sharing operate 180° out of phase to provide the fast  
transient response needed to satisfy high current applications  
while minimizing external components. The FAN5193 fea-  
tures remote voltage sensing and Programmable Active  
Droopfor 100nsec converter transient response with mini-  
mum output capacitance. It has integrated high-current gate  
drivers, with adaptive delay gate switching, eliminating the  
need for external drive devices. The FAN5193 uses a 5-bit D/  
A converter to program the output voltage from 1.10V to  
1.85V in 25mV steps with an accuracy of 0.5%. The  
FAN5193 uses a high level of integration to deliver load cur-  
rents in excess of 50A from a 12V source with minimal  
external circuitry. The FAN5193 also offers integrated func-  
tions including Power Good, Output Enable/Soft Start,  
under-voltage lockout,  
• 100nsec response time  
• Built-in current sharing between phases  
• Remote sense  
• Programmable Active Droop(Voltage Positioning)  
• Programmable frequency from 200KHz to 2MHz  
• Adaptive delay gate switching  
• Integrated high-current gate drivers  
• Integrated Power Good, OV, UVLO, Enable/Soft Start  
functions  
• Drives N-channel MOSFETs  
• Operation optimized for 12V operation  
• High efficiency mode (E*) at light load  
• Overcurrent protection using MOSFET sensing  
• 24 pin TSSOP package  
over-voltage protection, and adjustable current limiting with  
independent current sense on each phase. It is available in a  
24 pin TSSOP package.  
Applications  
• Power supply for PentiumIV  
• Power supply for Athlon  
• VRM for Pentium IV processor  
• Programmable step-down power supply
